'method of application, however, has the defeet, that the objects to becoated or pro tected must'be perfectly dry, otherwise they fail to pnitewith tar. Moreover, if the tar is very thick or viscous,it must berendered more liquid by heating, which is usually attended with dangerfrom fire, or it must be mixedwith organicsolvents, whereby the expenseof the process is considerably increased. I have found, that thesedefects may be avoided by preparing an emulsion of tar with clay, forinstance by stirring 200 kilograms of unctuous china-clay together withabout 100 kilos of water in a suitable mixing, machine, and thengradually adding about 500 kilos of tar and 200 kilos of water, whileconstantlystirring,

with the brush at ordinary temperature. As this emulsion contains water,it adheres to various kinds .of moist surfaces, such as iron, stone,cardboard and wood, and the' paint or coating has the propertycharacteristic of clay-tar emulsion, that after drying,

it is no longer absorbed by water. The paint is therefore perfectlyweather-proof and owing to the, presence of clay, it possesses thefollowing valuable properties.

'Unlike ordinary tar-coatings, it W111 not soften at high temperature,and consequently not, flow ofi',-while tarred roofing gradually losesthe major part of'its' tarcoating, when exposed to the heat of the sun.Moreover, the tar-clay aint is far less'com'bustible, and woodwork orroofing very slowly.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
